Air filter
Generally air filters come in two different types, a
pleated-paper element or foam. A combination of the two
are
used on the MTD engine. See Figure 1.3.
1. The main function of the air filter is to trap air borne
particles before they enter the engine. Dirt ingestion
can cause serious internal engine damage.
2. Air filters used on the MTD engine are designed to
prevent particles larger than 3-5 micron from passing
through into the engine.
3. The filter should be checked on a regular basis possi-
bly several times in a season.
4. Typically an air filter should be changed before every
season.
5. If a foam air pre-cleaner is dirty, but not in bad of con-
dition, it can be cleaned and reused. The paper
pleated filters can be shaken or lightly tapped to free
the debris from the filter.
NOTE: Never use compressed air on a paper air filter. Compressed air will remove the tiny fibers that are used
to catch the dirt in the air. Without these fibers the filter is useless.
6. Foam pre-filters can be washed in warm soapy water.
NOTE: When drying a foam filter either squeeze it inside of a paper towel or let it air dry. DO NOT wring it
because the filter will tear.
7. Before installing any foam filter, after it has been washed, it needs to be free of moisture.
NOTE: Always check with factory specification prior to servicing/replacing any engine components.
NOTE: Do not oil the foam pre-filter. The paper filer will absorb the oil and it will become plugged.
